Firstly, there is no proof God exists. Secondly, there is an astonishing amount of scientifical evidence of how the Earth came to be and of the existance of evolution. One cannot "believe" in evolution as evolution is a fact, in the same way one cannot believe in the existance of a chair or a table. Obviously, there isn't any evidence that God doesn't exist but to say that there is no evolution and that Earth is only a 1000 years old puts you on par with the twats who were sure the Earth was flat. They however had the excuse of living in an age where science was still laughably basic.
This excerpt from Carl Sagan's Cosmos (I suggest you read it, maybe it might make you less ignorant of science) even though something tells me that you won't bother to read it but it's a beautiful piece of text so I'm copying it anyway:
"Many people were scandalised - some still are - at both ideas, evolution and natural selection. Our ancestors looked at the elegance of life on Earth, at how appropriate the structures of organism are to their functions, and saw the evidence for a Great Designer. The simplest one-celled organism is a far more complex machine than the finest pocket watch. And yet pocket watches do not spontaneously self-assemble, or evolve, in slow stages, on their own, from say, grandfather clocks. A watch implies a watchmaker. There seemed to be no way in which atoms and molecules could somehow spontaneously fall together to create organisms of such awesome complexity and subtle functioning as grace every region of the Earth. That each living thing was specially designed, that one species did not become another, were notions perfectly consistent with what our ancestors with their limited historical records knew about life. The idea that every organism was meticulously constructed by a Great Designer provided a significance and order to nature and an importance to human beings that we crave still. A Designer is a natural, appealing and altogether human explanation of the biological world. But, as Darwin and Wallace showed, there is another way, equally appealing, equally human, and far more compelling: natural selection, which makes the music of life more beautiful as the aeons pass.
The fossil evidence could be consistent with the idea of a Great Designer; perhaps some species are destroyed when the Designer becomes disatissfied with them, and new experiments are attempted on an improved design. But this notion is a little disconcerting. Each plant and animal is exquisitely made; should not a supremely competent Designer have been able to make the intended variety from the start? The fossil record implies trial and error, an inability to anticipate the future, features inconsistent with an efficient Great Designer."
